My example of one is not statistically relevant. Nevertheless, sort of as an experiment I drove 628 km (390 miles) in light traffic from New Jersey to Quebec. Where possible, I drove at a steady state of 3000 rpm = 100 kph (+/- 62 mph) with the gearing that my car has (7:31).

I got 7.78 liters per 100 km (30.2 mpg U.S.). The car is a 1974 coupe, but has a '75, 2.7L S engine with C.I.S.

Edit: My engine is totally stock.
